Small sips can be easier than a full glass
Drinking enough supports your circulation and digestion. Dehydration can add to dizziness and fatigue, especially when nausea limits your intake. Fluids may help you feel better, but they do not treat every cause of fatigue or cure severe pregnancy vomiting.
ACOG recommends 8 to 12 cups of water a day, or 64 to 96 ounces, during pregnancy. Spread drinks through the day. Heat, exercise, and vomiting can change your needs; ask for an individual plan if you have a heart or kidney condition or a fluid restriction. ACOG water guidance
Fluids to try when you feel sick
- Chilled water, ice chips, or water lightly flavored with fruit.
- A commercial oral rehydration solution after repeated vomiting, if your clinician recommends it. Mix powders exactly as directed.
- Broth or clear soup for variety.
- Pasteurized milk or a fortified alternative when you can tolerate it.
- Small amounts of diluted juice or a caffeine-free drink if plain water is difficult.
Try a few sips every few minutes and increase gradually. Drinking between meals may be easier. Sports drinks are not the same as oral rehydration solutions; routine electrolyte powders are usually unnecessary when you are eating and drinking normally. Avoid energy drinks and unreviewed herbal blends.
Do not wait until you are severely dehydrated
Contact your OB promptly for reduced urination, persistent dizziness, or inability to keep liquids down. Early treatment may prevent dehydration from getting worse, but no drink guarantees that you will avoid an ER visit.
